No one had been able to take ownership of this conduit for many years until Marvin came into contact with it. Marvin met the requirement to use the conduit. This allowed him to begin his journey towards immortality.

It is also a conduit of great power. This power and many more will be his as long as he continues to sit on his mountain and grows the mountain into a colossus. The mountain will bring him to greater heights and greater power. This is the story of the Mountain Sitting Immortal.

- Description from Novelupdates

After a shocking reincarnation, our hero opens her eyes to a new (and messy) world the last thing she remembers is reading Lady Viper’s Vow, a dark fantasy novel about a cruel, misunderstood villainess and her path of doom. But when our protagonist finds herself reborn right in the heart of an attack, she’s moments away from a second, way-too-soon death. Just as she’s about to face the end, a mysterious “system” pops up with a single mission: Level Up or Die Trying. It’s bossy, snarky, and her new best friend. As she levels up into a borderline-cheater powerhouse, she discovers her fate isn’t to be a hero, a princess, or even a sorceress, but to protect the one person no one ever expected her to side with: the villainess herself.
